FIG. 9A is a diagram for explaining horizontal writing scrolling of telop information. The telop information is displayed in order from the telop information shown in the upper one line, and as a result, the telop information is displayed in the display area from left to right. A state of scrolling is shown.
FIG. 9B is a diagram for explaining vertical scrolling of telop information, and shows a state in which scroll display is performed from the bottom to the top as shown on the right side sequentially from the telop information shown in the left one line. .

Next, the operation of the telop information display device of the present invention will be described with reference to a flowchart.
FIG. 10 is a flowchart for explaining processing in a case where an image to be displayed is input or selected by the input unit 40 and the image confirmed in FIGS. 4, 5, and 7 is displayed in the display frame.
This flowchart is realized by the control unit 10 reading a program stored in the recording medium 100 of the present invention and sequentially executing each step. The same applies to the flowcharts described below.

  When the display of the image information is instructed by the user or the telop information display device, the head pointer of the program data (ProgD1) in the display frame 1 shown in FIG. 8A stored in the program information storage unit 140 in step S101. To get. As shown in FIG. 1. In step S102, it is determined whether the pointer is NULL. If it is NULL, there is no program, so this flow ends. If not NULL, the process proceeds to step S103, and the display time (Vt) of the program pointed to by the pointer Pt is acquired. According to FIG. 8A, the program data (ProgD1) No. of the display frame 1 is displayed. Since the display time of the content of 1 is 300 seconds, this is set. Next, in step S104, the content file pointed to by the pointer Pt is displayed. In this case, according to FIG. 8A, the content move1.mpg is displayed. Then, in step S105, measurement of display time is started. In the next step S106, the program data (ProgD1) No. of display frame 1 is displayed. It is determined whether 300 seconds or more, which is a display time (Vt) of 1, has elapsed. If yes, the process proceeds to step S107, the pointer Pt is changed to the next program, and the process returns to step S102. When all the programs have been reproduced, the pointer Pt becomes NULL, and this flow is finished through step S102.

No. of the program data (ProgD1) whose display time is display frame 1 When the display time is equal to or shorter than the display time (Vt) of 1, the process proceeds to the next step S108 to determine whether the content is a moving image. If it is not a moving image but a still image, the process returns to step S105 and continues to measure the display time. If it is a moving image, it is determined in step S109 whether or not the reproduction has ended. If the reproduction has not ended, the process returns to step S105, and the measurement of the display time is continued. When the reproduction ends, the process proceeds to step S110, and the content file is repeatedly reproduced, so that the process returns to step S105 so as to start reproduction from the beginning.
In this way, the image information set in the program data (ProgD1) is displayed in the display frame 1.
Similarly, program information set in the display frame 2 also displays image information.

Next, the procedure for generating control data in the case of the normal display in which the image information displayed in the display frame displays image information that does not cooperate with the telop information and the cooperative display in which image information that cooperates with the telop information is displayed. explain. That is, a procedure for generating control data for interrupting the display of image information linked with telop information when normal image information not linked with telop information is displayed in the display frame will be described.
FIG. 11 shows a flowchart for generating control data for controlling an image to normal display and cooperative display.
First, in step S201, it is determined whether or not the update flag of the normal display data of the display control data (Mem1) of the display frame 1 shown in FIG. If the update flag is not 1, that is, if it is 0, the process proceeds to step S202.

If the update flag is 1, the process advances to step S207 to determine whether the content of the normal display data is NULL. If it is NULL, there is no image information to be displayed, so the process proceeds to step S209, and black image data is created and set on the memory for normal display output in order to set the image information display frame to a black screen. Then, the process proceeds to step S210. If it is not NULL in step S207, the process proceeds to step S208, where the content data of the normal display data is read from the image data storage unit 120 and set on the normal display output memory. In this case, as shown in FIG. 6, it indicates that image2.jpg has been set. Then, the process proceeds to step S210. In step S210, in order to indicate that the update has been completed, the update flag of the normal display data is set to 0, and the process proceeds to the next step S202.

  In step S202, it is determined whether or not the update flag of the cooperative display data of the display control data (Mem1) is 1. If the update flag is 0, the process proceeds to step S203, and if the update flag is 1, the process proceeds to step S211. Steps S <b> 211 to S <b> 214 are controls when the cooperative display interrupts with the telop display. This control is almost the same as steps S207 to S210 described above, and only the normal display is changed to the linked display, and thus the description thereof is omitted.

  In step S203, it is determined whether or not the content of the linked display data of the display control data (Mem1) is NULL. If there is content, the process proceeds to step S204, and the data in the cooperative output memory is transferred to the display unit 50. If NULL, the process proceeds to step S205, and the data in the normal output memory is transferred to the display unit 50. In step S206, it is determined whether or not the program is finished. If it is finished, this flow is finished. If not completed, the process returns to step S301.

Next, display control of telop information will be described.
FIG. 12 shows a flowchart of display control of telop information.
When display of an image is instructed by the user or the telop information display device, the head pointer of the telop program data (ProgT) shown in FIG. 8B is acquired in step S301. In step S302, it is determined whether the pointer Pt is NULL. If it is NULL, this flow is terminated. If it is not NULL, the process proceeds to step S303, and it is determined whether there is image information associated with this telop information.

If there is image information to be linked, the process proceeds to step S304, and display control data (Mem1) for the display frame shown in FIG. 6 is acquired. That is, the content file name to be linked to the content of the display control data Mem1 of the linked display frame 1 is set, and the update flag is set to 1. In the example shown in FIG. 6, move1.mpg is set as the content file name. Then, the process proceeds to step S305.
If it is determined in step S303 that there is no linked image information, the process advances to step S305 to determine whether the display direction of the telop information is horizontal writing. When the display direction is horizontal writing, the process proceeds to steps S306 to S315, and when the display direction is vertical writing, the process proceeds to steps S316 to S325. Since the same control is performed when the display direction is horizontal and vertical, the display in the horizontal direction will be described here.

When the display direction of the telop information is horizontal writing, the process proceeds to step S306, and the telop program data ProgT pointed to by the pointer Pt is acquired in FIG. 8B. That is, at first, the telop No. For 1, the character string, font type, font data, etc. of the telop information are acquired, and a character string image in which the telop data is arranged horizontally is established on the memory. In step S307, the length (CW) of the character string is acquired from the character string image on the memory. In step S308, the program indicated by the pointer Pt, that is, the telop No. The width DW of the telop display area is acquired from 1. FIG. 13A shows the relationship between the display character string length CW and the display area width DW.
FIG. 13B shows the relationship between the display character string length CW and the display area width DW when the display direction of the telop information is vertical writing.

In step S309, the character string image arrangement position Po is set to Po = X coordinate + DW. That is, the X coordinate + DW is substituted for Po. In step S310, a telop frame is generated from the program coordinates indicated by the pointer Pt, the width, the height, and the background color, and is arranged at the coordinate position on the memory. In step S311, the character string image is arranged at the coordinates (Po, Y coordinates) of the telop frame on the memory. This is shown in FIG. In FIG. 14A, the left end of the telop character string is at the right end of the telop display area, and the telop display starts. FIG. 14B to FIG. 14H show that the telop character strings are sequentially scrolled to the left and displayed as time elapses.
In step S312, the image in the telop frame range on the memory is transferred to the screen. In the next step S313, whether the character string image arrangement position Po is equal to or less than (X coordinate−CW), that is, as shown in FIG. 14H, the right end of the telop information reaches the left end of the display area, and the telop display is It is judged whether it is finished. If no, the display of the telop information has not been completed, so the process proceeds to step S314, and the moving amount dM calculated from the preset display speed is subtracted from the character string image arrangement position Po. That is, Po = Po−dM is calculated. Then, the process returns to step S310. Thereafter, by repeating this operation, the telop information is scrolled to the left.

If yes in step S313, the display of the telop information has ended, and it is determined whether or not the number of reproductions has been reproduced. If the number of reproductions has not been reached, the process returns to step S309. If the number of times of reproduction has been reached, the process proceeds to step S326, and the content file name linked to the content of the display control data Mem1 of the linked display frame is set to NULL. In step S327, in order to change to the next program, the pointer Pt is incremented to change to the next program, and the process returns to step S302.
The above flow is repeated, and when all content files are NULL, the flow is terminated through step S302.

  As described above, steps S306 to S315 are a flow when the display direction is the horizontal direction. However, when the display direction is the vertical direction, in step S316, the character string images arranged vertically are established, and in step S317, the display is performed. The character string length (vertical writing) is changed to CW, the height DW is changed in step S318, the Y coordinate is changed in step S319, and the Y coordinate is changed in step S323. Others are the same.

Finally, two methods for detecting the end of display of telop information will be described.
The first is a method of detecting the end of reproduction from the display position of telop information.
FIG. 15 shows a flowchart for detecting the end of reproduction from the display position of the telop information.
When the telop information is displayed, it is determined whether the telop information is horizontal writing (step S401). When the telop information is horizontal writing, it is shown in steps S402 to S410. If the telop information is vertical writing, it is shown in steps S411 to S419.

  In step S402, the horizontal width of the telop display area is set as a display area (DW). In step S403, the total width of the telop display characters is set as the character string length (CW). This is as shown in FIG. In step S404, the left end of the character string is arranged at the right end of the telop display area. That is, as shown in FIG. 14A, the head of the telop character string is arranged at the display start position of the display area. In step S405, the counter is initialized. That is, I <−0. In step S406, the display of telop information is updated.

In step S407, the left end of the character string is arranged at a position of I × V from the right end of the telop display area. In step S408, it is determined whether I × V is equal to or greater than the sum of the telop character string length CW and the horizontal width DW of the telop display area. If I × V is less than or equal to the sum of the telop character string length CW and the horizontal width DW of the telop display area, the process proceeds to step S409, the counter is incremented, and the process returns to step S406. If I × V is equal to or greater than the sum of the telop character string length CW and the horizontal width DW of the telop display area, it is determined in step S410 whether or not the number of reproductions has been completed. If no, the process returns to step S404. If yes, this flow ends.
The meaning of determining the total of the telop character string length CW and the horizontal width DW of the telop display area in step S408 is that the telop character string is not displayed in the telop display area as shown in FIG. As shown in FIG. 14 (h), this indicates until no telop character string is displayed.
The flowchart of FIG. 15 is a case where there is a blank period from the start of display of the telop information until the display of the telop information is ended, as shown in FIG. 14H, as shown in FIG. However, when displaying a telop character string without a blank period, the telop character string length CW may be used as a criterion for determination, not the sum of the telop character string length CW and the horizontal width DW of the telop display area.

  If the telop information is vertical writing, the flow from step S411 to step S419 is executed. This flow is the same as that in steps S402 to S410 except that the vertical width is set in step S411 and the upper end and the lower end are changed in steps S413 and S416. Note that the character string length CW of the telop information in the case of vertical writing is the character string length in the vertical direction as shown in FIG. In the display area DW, the vertical height of the telop information display area 2 is DW.

Part 2 of the method for detecting the end of display of telop information is a method for detecting the time from the start of display of telop information.
The display time T of the telop information can be obtained by the following equation.
T = {(CW + DW) / V ×} Number of playbacks where V is the display speed.
Based on this equation, it is possible to detect the end of display of telop information based on the time from the start of display of telop information using the flowchart shown in FIG.

First, it is determined whether the telop information is horizontal writing (step S501). The case where the telop information is horizontal writing will be described in step S502 and step S503. If the telop information is written vertically, it will be described in step S504 and step S505.
When the telop information is written horizontally, in step S502, the width of the telop display area is set as the display area (DW), and in step S503, the total width of the telop display characters is set as the character string length (CW).

If the telop information is vertical writing, the width of the telop display area is set as the display area (DW) in step S504, and the total height of the telop display characters is set as the character string length (CW) in step S505.
Next, in step S506, the display time T of the telop information is calculated using the above formula, and this flow ends.

The flowchart of FIG. 16 also shows a case where there is a blank period from the start of display of telop information to the end of display of telop information, as shown in FIG. However, when the telop character string is displayed without a blank period, the telop character string length CW and the horizontal width DW of the telop display area may be used instead of the sum of the telop character string length CW.
